- n. The ultimate standard of mass in the French system of weights and measures, equal to 1,000 grams; the mass of a certain cylinder of platinum deposited in the Archives of France on the 22d of June, 1799, and thence known as the Kilogramme des Archives. But in future the ultimate standard will be the international kilogram at the Pavilion de Breteuil near Sèvres; this substitution will not alter the value of the kilogram. The kilogram was intended to be (and is, within one ten-thousandth part) the mass of a cubic decimeter of water at its maximum density. It was ascertained by Miller to be equal to 15432. 34874 grains, or 2. 20462125 imperial pounds, with a probable error of 3 in the last decimal place. An independent determination by Miller (made merely as a check upon the other) gave 2. 20462116, with a probable error of 5 in the last place. The real error, however, and indeed the variations of weight of this ill-constructed Kilogramme des Archives, may very likely be somewhat greater. See
